SNA´19 - Seminar on numerical analysis.
Blaheta, Radim ; Starý, Jiří ; Sysalová, Dagmar
Seminar on Numerical Analysis 2017 (SNA'17) is a continuation in a series of SNA events held\nin different places in the Czech Republic and organized alternatively by Ostrava and Prague\ninstitutions. The SNA'17 is organized by the Institute of Geonics of the CAS in collaboration with\nVŠB - Technical University of Ostrava and IT4Innovations National Supercomputing Centre.\nConference location is one of the lecture rooms in New Aula of the VŠB-TU Ostrava.\nLet us note that SNA 2016 was reshaped to EMS School in Applied Mathematics (ESSAM)\ndevoted to mathematical modelling, numerical analysis and scientiffc computing. The SNA'17\nis turning back to more traditional winter event.\nIt provides opportunity for meeting and mutual information of the community working in computational\nmathematics and computer science, but an important part of SNA is devoted to the\nWinter School with tutorial lectures focused on selected important topics within the scope of\nnumerical methods and modelling.\nThis year, a part of the Winter School will be the course Parallel Linear Algebra (PLA) organized\nby the European research infrastructure PRACE, particularly by the French PRACE Advanced\nTraining Centre - Maison de la Simulation. Winter school lectures will cover the ongoing topics\nrelated to domain decomposition methods, interval computations and numerical veriffcation. The\nPLA course will provide lectures from the area of direct and iterative parallel solvers, as well as\npractical training with selected programs.

Concept of body in Old Norse literature
Novotná, Marie ; Komárek, Stanislav (advisor) ; Horáček, Ivan (referee) ; Starý, Jiří (referee)
This work attempts to outline concepts associated with body in the Old Norse literature. As the word for the body (líkamr) as well as the term for an incorporeal soul (sál) do not occur in the Old Norse literature until the translated Christian works and cannot therefore be used as markers, two areas closely connected with the concept of body have been chosen for the research: shifting of shape (hamr) and somatic expressions of emotions. In the first area, i.e. phenomena associated with shape-shifting, contexts of all (113) occurrences of radix ham- in the Old Norse literature are analysed in order to describe the semantical field of this root. Within the themes that have appeared in the material (i.e. shape-shifting related to flying, battle frenzy and magic), occurrences are ordered on an axis from those where the form (hamr) is considered to be holistic to those where just the form of body or soul is described. In this context, it is important to mention the proximity of man and animal in the Germanic environment, as shape-shifting is often related to an animal and thus points to the limits of human identity. In the second area, i.e. somatic expressions of emotions, we can also find cases where the mental and the physical area intersect and the boundaries between diseases and emotions are not...

A Comparison of William Morris' The Story of Sigurd the Volsung and the Fall of the Niblungs and J. R. R. Tolkien's The Legend of Sigurd and Gudrún
Hlavatá, Barbora ; Starý, Jiří (advisor) ; Znojemská, Helena (referee)
This thesis focuses on the formal and stylistic analysis and comparison of two works written by English authors, namely William Morris' poem The Story of Sigurd the Volsung and the Fall of the Niblungs (1876) and J. R. R. Tolkien's poetic work The Legend of Sigurd and Gudrún (published posthumously in 2009) with respect to how each of these works deals with the original Old Norse motives which they are based on. Both Sigurd the Volsung and The Legend of Sigurd and Gudrún can be described as poetic adaptations of the Old Norse tale of Sigurd Fafnisbani, which is recounted in the Saga of the Volsungs and in a cycle of poems found in the Poetic Edda. Both Morris and Tolkien borrowed this story to use it in their own works, yet each of them treats it in a different manner. Therefore, not only do both of the works differ from the original Old Norse texts on multiple levels, but they also differ one from another. The differences between them can be traced in the metrical properties of the individual poems, for instance, or in the use of specific stylistic elements. From this, it can be inferred that although it was the goal of both authors to evoke the atmosphere of the legendary heroic past where Sigurd's story takes place, each of them attempts to do so in a different way. This is probably caused by...

Solder Joint Strength Measuring
Konečný, Aleš ; Chladil, Ladislav (referee) ; Starý, Jiří (advisor)
This thesis studies the definition of solder joint strength and its contributing factors. It also evaluates the options provided by using a MARK10 M5-100 digital force gauge with MESURgauge software for measuring solder joint strength and practically tests solder joint strength of SMD components sized 1206, 0805 and leads of THT components. Based on this, the thesis suggests further tests to be done in order to evaluates the degree to which each factor affects solder joint strength and suggests possible improvements of testing procedures used. These tests and improvements will be explored by a follow-up thesis, which will also be creating a part of a guide to a new laboratory exercise.

SnBi Solder Paste and Influence of Reactive Nanoparticles
Rychlý, Ivo ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
This work deals with effects of nanoparticles, mainly copper and silver, on properities of lead-free solder pastes. It describes basic tests done on solder pastes according to IPC-TM-650 standards. In practical section this work focuses on the preparation of Sn-Bi solder paste and the measuring of viscosity. After that different concentrations of silver copper alloy nanoparticles are added to the SnBi solder paste. These solder pastes are tested by the IPC standarts and mechanical and resistive tests are done on printed circuit boards where the effects of mixed in nanoparticles are observed.

Flux Selection for Wave Soldering
Dyntarová, Markéta ; Jan, Čermák (referee) ; Starý, Jiří (advisor)
The theoretical part of diploma thesis „Selection of a suitable type of flux for wave soldering”, is devoted to problematic of fluxes, flux residues and wave soldering. It introduces reader with requirements of company HC electronics and with selection of a suitable types of fluxes for testing. It also contains theoretical comparison and design of flux testing methodologies. The practical part of the diploma thesis is focused on the selection of a suitable flux for the company HC electronics by performing practical tests according to the previously proposed methodologies, which include wetting balance test method, surface insulation resistance measurement, copper mirror test, soldering test of PCB and ROSE method.

Quality of PCB Surface Finishes and Test Coupon Optimization
Minář, Jan ; Přikryl, Tomáš (referee) ; Starý, Jiří (advisor)
This master’s thesis deals with measuring and evaluation of wetting for samples of different surface finishes, using a test coupon developed in cooperation with firm Gatema. It deals with surface finishes ENIG and immersion tin. For these samples deals with quality monitoring and periodic testing of these surface finishes. The solder using for tests is SAC305. Test methods are used for simulation of reflow soldering and wave soldering.
